Makernice Team · 2026-11-11 · Updated 2026-11-12 ## Key takeaways - Atlas Cloud, CometAPI, Crun, Makernice and WaveSpeedAI each list most of the Seedance, Kling, Wan and MiniMax models MuAPI sells, and none of them requires a monthly subscription. - MuAPI deducts prepaid credits per generation, offers an estimate endpoint for the price of a specific request, and says its credits never expire; on the pages we read it gives no rule for failed tasks or file retention. - Those open points are where the alternatives differ: Atlas Cloud and Makernice don't charge failed tasks (Makernice still charges an output blocked by output moderation), WaveSpeedAI refunds failed requests automatically, CometAPI doesn't bill upstream 5xx errors, and Crun deletes generated files after 14 days. - Keep MuAPI if you work in its Studio, Workflow or Agents pages, need models outside video and image, or want its small free credit allocation before paying.

The best MuAPI alternatives for the same video and image models are Atlas Cloud, CometAPI, Crun, Makernice and WaveSpeedAI, and the right one depends on which of MuAPI's unstated rules matters to you. All five sell pay-as-you-go access to most of the [Seedance](https://makernice.com/models/seedance-2-0/), [Kling](https://makernice.com/models/kling-3-0-standard/), Wan and [MiniMax](https://makernice.com/models/minimax-h3/) models on MuAPI, with no monthly subscription. They part ways on the points MuAPI's pages leave open: whether a failed task costs credits, how long outputs stay downloadable, and whether a price is settled before the job starts. Every platform here was checked on November 11, 2026. ## What is MuAPI, and how does it meter usage? MuAPI calls itself a "Generative AI API Platform" on muapi.ai (checked November 11, 2026), with Studio, Workflow, Agents and Apps pages around the API. Its docs explain that "MuAPI uses a credit-based system to meter API usage. Credits are purchased in advance and deducted per generation." You choose a top-up amount and pay through Stripe, send an `x-api-key` header with each call, and can submit a task with a webhook so the result is pushed back to you. MuAPI states "Credits never expire." and gives new accounts a small free allocation. For pricing ahead of a run, the docs point to an estimate endpoint, telling you to "use the estimate endpoint below to get the exact price for a specific" request. Three things we could not find stated: whether a failed task is charged (response examples only carry a refunded field), how a cancelled task is billed, and how long generated files are kept. The refund policy reads "All credit purchases are non-refundable once used". ## Which MuAPI alternatives sell the same models pay-as-you-go? Atlas Cloud, CometAPI, Crun, Makernice and WaveSpeedAI all sell prepaid, pay-as-you-go access to most of the Seedance, Kling, Wan and MiniMax models on MuAPI, and none of the five needs a monthly plan. Crun is the only one that sells credits in fixed plan sizes. | Platform | Best for | How it bills | Source checked | | --- | --- | --- | --- | | Atlas Cloud | One balance that also pays for chat and audio models, with MCP and CLI access | Cash balance with a minimum top-up; the exact charge is computed when a task completes; credits expire after 365 days | [atlascloud.ai](https://www.atlascloud.ai/models/bytedance/seedream-v5.5/text-to-image) · 2026-11-11 | | CometAPI | Trying models on free trial credits with no minimum spend | Prepaid credits, per image or second for media and per token for text; credits last while the account is in good standing | [cometapi.com](https://www.cometapi.com/pricing/) · 2026-11-11 | | Crun | Buyers who want more credits per dollar on a larger plan | Credit plans in four sizes; per-request pricing, with final charges following actual usage | [crun.ai](https://crun.ai/pricing) · 2026-11-11 | | Makernice | Apps and agents that need the price settled before each run | Prepaid US-dollar balance, per output second or per image; no subscription and no expiry | [Makernice pricing](https://makernice.com/pricing/) · live price list | | WaveSpeedAI | Developers who want refunds for failed requests written down | Pay-per-use balance with no monthly fee; the balance never expires | [wavespeed.ai](https://wavespeed.ai/pricing) · 2026-11-11 | Rates are left out of this table on purpose. The [MuAPI alternative page](https://makernice.com/alternatives/muapi/) lines up per-second prices for matching models and resolutions from each platform's published list, with the date of every check. ## What each MuAPI alternative does differently **Atlas Cloud** describes itself as an aggregation platform for image, video, audio and chat models, and it matches MuAPI on nearly every video and image model we track. It says "Failed tasks are not charged", yet the number shown before a run is provisional, since the final cost depends on the output and is worked out at completion. Bought credits lapse a year after purchase, a minimum applies to each top-up, purchases are final, and outputs stay for 14 days unless you set otherwise. It takes Stripe cards, Alipay and cryptocurrency, and it was paying back part of MCP and CLI spend as credits when we looked. **CometAPI** bills "per token for text models and per image/second for media models" from prepaid credits, and its pricing page promises "no monthly fee, no minimum spend, and no subscription." Its refund policy splits cases finely: a request forwarded upstream that returns a 5xx error costs nothing, a generation cut off mid-stream is billed for what was produced, and inputs rejected for policy reasons are reviewed one by one. Model pages show test estimates for 5, 10 and 15 second clips, though we saw no promise that those figures are held. CometAPI says it does not store prompts, inputs or outputs, so save results as they arrive. **Crun** sells credits in four plan sizes, and each step up adds a few percent more credits per dollar. Its pricing page lists estimates and adds "Final charges are based on actual official Token usage." Generated media is "stored for 14 days, then automatically deleted", and uploaded inputs are wiped within 3 days. The docs cap new generation requests at 20 per 10 seconds. Crun offers a free trial, but we found no statement about failed-task charges or whether credits expire. **Makernice** has a narrower scope than MuAPI: 19 video and image models, an API and an MCP server, and a console form for single runs, with no workflow builder or editor. In exchange, the price is settled before any work begins. A REST quote holds for 12 minutes and the job is created from its id; over MCP, `generate` prices the job again and refuses it if the figure is above the `max_cost_usd` the user approved, and the charge equals that figure. Failed, timed-out and input-rejected runs aren't charged, while an output stopped by output moderation is still charged. Every output carries an `expiresAt` time, 30 days after completion in the docs example, and results arrive by polling, a per-job `callback_url` or an account [webhook](https://makernice.com/docs/#webhooks). **WaveSpeedAI** carries all of MuAPI's Seedance, Kling, Wan and image models that we track, missing only the two MiniMax H3 Max variants. Its refund policy separates failures from client-side problems: failed requests get an automatic refund, while a sync-mode client timeout is not refunded if the task keeps running and completes. There are "no monthly fees or commitments", the balance never expires, and rate limits rise with an account level set by the size of a single top-up. Media files "generally expire within 7 days", so copying outputs out quickly matters more here. ## Failed tasks, file lifetime and price certainty compared MuAPI leaves failed-task charges and file lifetime unstated, so those two rules, plus price certainty and credit lifetime, separate the five MuAPI alternatives most. - **Failed tasks:** MuAPI doesn't state a rule. Atlas Cloud and Makernice don't charge them, WaveSpeedAI refunds them automatically, CometAPI doesn't bill upstream 5xx errors, and Crun doesn't say. Makernice's rules are on its [failed generations](https://makernice.com/pricing/failed-generations/) page. - **File lifetime:** MuAPI gives no period. Atlas Cloud keeps outputs 14 days by default and Crun 14 days, WaveSpeedAI generally under 7 days, CometAPI stores nothing, and Makernice sets an `expiresAt` per output. - **Price before a run:** MuAPI has its estimate endpoint and CometAPI shows test estimates. Atlas Cloud computes the charge at completion, Crun bills on actual usage, and WaveSpeedAI shows an estimate with the final task charge prevailing. Makernice holds a REST quote for 12 minutes, or caps an MCP job at `max_cost_usd`. - **Credit lifetime:** MuAPI, WaveSpeedAI and Makernice balances don't expire, CometAPI credits last while the account is in good standing, Atlas Cloud credits expire after 365 days, and Crun doesn't say. ## When should you keep MuAPI instead of switching? Keep MuAPI if its web features carry part of your work, since Studio, Workflow, Agents and Apps sit next to its API and Makernice offers only a console form for single runs. Keep it if you also call models outside video and image, because its catalog reaches well past what Makernice serves. If its estimate endpoint already gives you the price you need before each run, the remaining gap is the unstated failed-task rule, which is worth confirming with MuAPI before you move anything. The [MuAPI alternative page](https://makernice.com/alternatives/muapi/) walks through switching one workflow at a time. ## Frequently asked questions #### Does MuAPI charge credits when a task fails? The MuAPI pages we checked on November 11, 2026 don't say; its response examples only include a refunded field. Atlas Cloud and Makernice state that failed tasks aren't charged (Makernice still charges an output blocked by output moderation), and WaveSpeedAI refunds failed requests automatically. #### Is MuAPI's estimate endpoint the same as a locked quote? MuAPI tells developers to "use the estimate endpoint below to get the exact price for a specific" request, and we found no statement that the price is held for a set time. Makernice holds a REST quote for 12 minutes, and its MCP generate tool refuses a job priced above the approved cap. #### How long do MuAPI's alternatives keep generated files? Makernice's docs example shows 30 days after completion, Atlas Cloud and Crun keep files 14 days, and WaveSpeedAI generally under 7 days. CometAPI says it doesn't store outputs, and MuAPI doesn't publish a period. #### Is MuAPI free to start? MuAPI gives new accounts a small free credit allocation, then deducts prepaid credits per generation with no monthly subscription. Makernice has no free credits; estimate\_cost returns a price without creating a job or charging your balance. #### Can I keep an unused MuAPI balance after switching? MuAPI says "Credits never expire.", so leftover credits stay usable if you move only part of your traffic. Its policy also says purchases are non-refundable once used.
